Texas Instruments UCCx8C5x/UCCx8C5x-Q1 Current-Mode PWM Controllers
Texas Instruments UCCx8C5x/UCCx8C5x-Q1 Current-Mode PWM Controllers offer a high-performance solution that can drive both Si and SiC MOSFETs in various applications. The UCCx8C5x/UCCx8C5x-Q1 is a more efficient and robust version of the UCCx8C4x/UCCx8C4x-Q1. The devices provide unique UVLO thresholds that enable a reliable SiC MOSFET operation (UCC28C56-59) and existing UVLO thresholds for continued Si MOSFET support (UCCx8C50-55).
The TI UCCx8C5x/UCCx8C5x-Q1 current-mode PWM controllers are available in 8-pin VSSOP (DGK) and 8-pin SOIC (D) packages.
